TOBAGO() PIPE.

Application led March 3, 1923. Serial No. 622,583.

To all whom il? may cof/wem:

Be it known that I, ALFRED HACKETT, a subject of the King of GreatBritain, residing in the city of Toronto, county of York, Province ofOntario, Canada, have invented certain new and useful Improvements inTobacco Pipes, of which the f ollowing is a specification.

My invention relates to improvements in tobacco pipes, and the principalobject of l my invention 1s to construct a tobacco pipe which willinsure at all times theffreedom from saliva of the tobacco in the bowl,thus insuring a sweet smoke. Another object of my invention is toconstruct my pipe so that the mouth piece may be readily removed Thestem A of the bowl B is provided' with a uniform bore C for the majorportion of its length, larger than the usual bore, and

` this uniform bore is provided with theuniform lining D, made of metal.There is no necessity of removing the lining D when it has been placedin position, as the neck E of the mouth piece F is removably sup- Yported in the outer end of said lining, which outer end is .preferablyflanged as Shown at 4 Gr so as to face against. the outer end of thestem A. rlhe inner end I-I of said lining is closed, except for anopening through which extends a conduit I. which ts a hole J formed inthe bottom of the bowl B and opening into the bottom of vthe cavity insaid bowl at one side thereof in the usual Way. This conduit I iscoupled to the lining D through the medium of the inner end H thereof sothat said conduit will be positioned when said lining 'is positioned.

Mounted within the mouth piece F and projecting beyond the inner endthereof into the lining D is a, conduit O, preferably the same diameteras the conduit I, and substanameter of the lining D.

The lined bore C, in combination with the conduits I and O, form a wellor trap, and it is evident that the saliva flowing down said conduit Owill pass into the said trap or Well, in place of continuing through theconduit I into the cavity of the bowl B.

It is believed that a considerable percentage of the waste products ofcombustion, so to speak, contained in the smoke from the smoulderingtobacco, as the smoke leaves the conduitI, will remain inthe well ortrap, thus appreciably reducing the percentage of suchV waste productsof ycombustion that reach the smokers mouth. Y

The tobacco in the bowl B will be free of admixture with the saliva, anda cooler and sweeter smoke will result.

What I claimy is:

A tobacco pipe having a bore of uniform diameter longitudinally formedin the straight stem thereof for the major portion of its length, theinner end of said bore terminating short of the cavity in the bowl; ametal lining of uniform diameter `having a circular inturned flange atits inner end permanently mounted in said bore, and having its flangedinner end fit against the inner end of said bore; a metal conduit havingits inner end mounted in that portion of the bowl of the pipe separatingthe inner end lof said bore from said cavity, and extending through theinner end of said lining; a mouth piece having v`a neck adapted to fitwithin the outer end of Said metal linin and a metal conduit mountedwithin sai mouth piece for the length thereof and extending beyond saidneck into said metal lining, the inner ends of said conduits beingspaced apart.

ALFRED HACKE'IT.
